Abstract
An apparatus for mating a finished ophthalmic lens includes a pre-manufactured lens or lens wafer as a part of a mold for making the finished lens. A polymerizable lens material is injected between the lens or lens wafer and a conventional mold member and a trio of indexers are used to rotate the conventional mold member relative to the lens wafer, to adjust the spatial relationship between the conventional mold member and the lens or lens wafer, and to control the angular relation between them. The assembly is subjected to irradiation and the radiation cures the polymerizable lens material and fuses it to the lens wafer so that the lens or lens wafer becomes an integral part of the finished lens. The apparatus produces a finished lens in less than one hour.
